DEVICE FOR OPERATING ON TRAVELING YARNS.

Application filed October 30. 1923.

To all whom it may concern:

Be it known that I, LoUIs B. HASBROUCK, a citizen of the United States,residing at Elmira, in the county of. Chemung and State of New York,have invented certain new anduseful Improvements in Devices forOperating on Traveling Yarns, fullydescribed and represented in thefollowing specification, and the'accompanying drawing, forming a part ofthe same.

This invention relates to a device for operating on a traveling yarn andaims to provide a device which will automatically adjust itself for,operation upon yarns of different sizes.

A further object of the invention is to provide such a device with meansfor adjusting it to operate upon yarns of diflferent characters, or tochange the nature of its operation.

A still further object of the invention is to provide a device foreliminating from a traveling yarn all slubs or bunches, includingbunches which are so soft that they would be drawn through an ordinaryslub catcher.

A device constructed in accordance with the invention has two separablecontrolling members which are gently urged together and have opposedsurfaces between which the yarn passes. Elements for operating upon theyarn are connected to these controlling members in such manner that thedistance between the operative elements is determined by the extent towhich the opposed surfaces of the controlling members are separated bythe yarn between them. In

. consequence, the operative elements, are automatically placed inproper position to operate upon a yarn of any sizeas soon as this yarnis drawn through the device so that it extends between the opposedsurfaces of the controlling members. A feature of the invention consistsin utilizing the tension of the traveling yarn to urge the-opposedsurfaces of the controlling members toward each other. This serves toprevent aocidental or momentary separation of these members during theoperation of the device.

In order to adapt the device to catching soft bunches or slubs whichwould pass between the blades of an ordinary slub catcher,

one of the operative elements is made in the Serial No. 671,747.

a bunch, no matter how soft, is drawn into the device, the fibers of thebunch become caught in the comb, so that the yarn is held and broken,permitting the removal of the bunch. A further feature consists in soarranging the device that the increased tension on the yarn caused bythe catching of a bunch on the comb serves to move the comb toward theyarn and thus to cause it to hold the bunch still more securely.

Other features and advantages of the invention are hereinafter setforth.

Although the broad features of the invention may be embodied in a deviceof any sort for operating upon a traveling yarn, the nature of theinvention may be understood from a description of an illustrativeembodiment adapted to eliminate bunches and slubs from cotton or worstedyarns. Such a slub catcher is shown in the accompanying drawings, inwhich Fig. 1 is a side elevation of the slub catcher;

Fig. 2 is a top view;

Fig. 3 is an enlarged side view sectioned on the line 33 of Fig. 2; A

Fig. 4 is an enlarged transverse section on the line elet of Fig. 2; and

Fig. 5 is a partial plan view sectioned on the line 55 of Fig.

The slub catcher shown in the drawings has a vertical supporting plate10 which may conveniently be mounted by securing it to a horizontal bar11 by means of a set screw 12. A flange extending from the upper edge ofthe plate 10 near its front end is bent over to provide a horizontalfront guide 14 having ears 15 between which the 'yarn is dropped inthreading the device.

On the front guide 14 is a tension device 16 which may takethe form of adisc 17 loosely mounted on a Stud 18 projecting upwardly from the frontguide.

A flange extending from the upper edge of the plate 10 near its middleis bent over to provide a horizontal bed 20 whose upper surfaceis at thesame level as that of the threading of the device. The bed 20 contains acentral opening 22 whose rear edge 23 is acute. The front portion 24of'the bed serves as one of the two operative or slubicatching elementsof the device, while the rear portion 25 of the bed serves as a controlling member cooperating with a movable controlling member or rest 30in determining the relative position of the two operative elements. Themovable controlling member 30 is, in the form shown, carried by a lever31.

The lever 31 is pivoted 'at one end on a horizontal stud 32 projectingfrom the side of the plate 10 opposite to that from which the bedprojects. The stud 32 is located nearer the front end of the plate 10than the bed and below the level of the. bed. A sleeve 33 secured to thelever and surrounding the stud prevents lateral movement of the lever.The controlling member or rest 30 is formed by a flange which extendsfrom the upperedge of the lever 31 near its free end and is bent over toextend across the upper edge of the plate 10 with its lower surface 34opposed to the upper surface 26 of the rear portion of the bed. Thelower front edge of the rest lies directly over the acute front edge 23of the rear portion 25 of the bed. The lower outer edge of the rest 30is bevelled at 35 (Fig. to facilitate drawing a yarn between thesurfaces 26 and 3st when the device is threaded. To the rest 30 issecured a comb which serves as the principal operative element of thedevice. The operative edge 41 of this comb is provided with sharp teeth42, and lies over the portion 24 of the 'bed 20 to cooperate with thisportion of the bed in catching slubs. In order that the position of theoperative edge 4L1 may be adjusted with re spect to the plane of thelower surface 3% of the rest 30, the upper surface 43 of the rest 30 isinclined to its lower surface and the rear portion of the comb is heldagainst this upper surface by a screw 44 passing through a longitudinalslot 45 in the comb. The comb 4:0 is narrower than the rest 30 so thatits operative edge ll does not extend as far out from the plate 10 asdoes the rest 30.

A flange extending from the upper edge of the lever 31 at its free endis bent over to provide a horizontal foot extending across the upperedge of the plate 10 behind the bed 20, and a downwardly curved ear 51at the outer end of the foot serving to guide the yarn onto the uppersurface 52 of the foot when the device is threaded.

A rear thread guide 55 is mounted on an arm 56 projecting rearwardlyfrom an upper part of the plate 10. The guide is secured to this arm bya bolt passed through a vertical slot 57 in the arm so that the guidemay be adjusted up or down. It is'normally positioned with the uppermostpart of its groove 58 located below a straight line extending from therear edge of the bed 20 over the foot 50, so that the yarn turnsdownward after passing over the foot.

To facilitate threading the device a guard 60 is secured to the plate10. This guard has a curved portion 61 which extends over the comb 40and has its end 62 located just above the inner end of the curved car21.

The use and operation of the device described is as follows :The deviceis threaded by dropping a yarn into the opening between the ears 15 ofthe front guide 14, into the opening between the guard (50 and the ear21, and passing the yarn over the rear guide 55. As soon as a forwardpull is applied to the yarn, it slips sideways under the tension disc17, under the rest 30, and over the foot 50. In slipping under the rest30, the yarn strikes the bevelled surface 35 of-the rest and raises therest and with it the comb 40. As the comb does not project as far out asthe rest, the yarn has raised the rest and the comb before it comesunder the operative edge ll of the comb and in consequence does notcatch in the teeth 42.

As the yarn travels through the device, the rest 30 rides on its uppersurface, and positions the operative edge ll of the comb l0 eitheradjacent to or at a desired distance above the upper surface of theyarn. Any specks or loose dirt adhering to the yarn are scraped from theyarn by the acute edge 23, and such dirt is thus prevented from onteringunder the rest 30 and raising it above the level of the upper surface ofthe yarn. The slight raising of the rest and the conse quent vibrationof the lever 31 which might be caused by irregularities in the yarnitself areprevented by the pressure of the yarn on the upper surface ofthe foot 50.

lVhen a slub is drawn into the device, some of its fibers becomeentwined in the teeth 4C2 of the comb 40 and the tension on the part ofthe yarn beyond the comb is thereby increased. The operative edge ll ofthe comb is then drawn down against the portion 2a of the bed, clampingthe slub between the comb and the bed, so that the yarn is broken. Twoforces contribute to this downward movement of the comb. The first isthe pull of the strands which are caught on the teeth of the comb, whichtends to draw the comb downwardly because of the fact that the pivot 32is located below and in front of the operative edge d1 of the comb. Thesecond downward force is the increased pressure of the yarn on the foot50 which is caused by the increased tension.

The position of the operative edge 41 of the comb with reference to theplane of the lower surface 34: of the rest 30 is adjusted in accordancewith the kind of yarn operated upon. This adjustment is made byloosening the screw a l and sliding the comb forwardly or rearwardly onthe inclined surface 43 until its operative edge 41 is in the desiredposition. The adjustment is ordinarily" such that the operative edge 41of the comb lies slightly above the plane of the lower surface 34 of therest 30 so that, when the rest is resting on the yarn, the operativeedge 41 of the comb is just out of contact with the upper surface of theyarn. The exact adjustment necessary'to obtain this result depends uJO11 the character of the yarn, and particular y upon its softness. Whenthe proper adjustment has once been obtained for a yarn of any givencharacter, the device automatically adjusts itself for operation on allother yarnsof the same character, regardless of their size. Furthermore,in case it is desired to break the yarn only when slubs projectingbeyond the predetermined distance from the yarn enter the de vice, thecomb maybe adjusted so that it lies at this distance from theuppersurface of the yarn. In this case also the adjustment of the combon the rest will remain the same for all sizes of yarn.

The pressure of the yarn on the foot should be very slight, so that theyarn will. not be pinched between the surfaces 84 and 26, but on theother hand this pressure shouldbe sufiicient to prevent the lever 31.from vibrating. The proper pressure may be obtained by adjusting therear guide in its slot 58, it being apparent that the fur ther down theguide is moved in its slot the greater the pressure of the yarn upon thefoot 50.

The device has proved to be highly efficient when used either withcotton or with worsted yarn and is I believe the first device of thischaracter in which the relative position of the operative elements isautomatically adjusted in accordancewith the size of the yarn, and thefirst device capable of batching the soft bunches found on worstedyarns. As novel principles have been utilized 'to accomplish theseresults, I wish it clearly understood that the invention is by no meanslimited to the form and arrangement of the parts of the illustrativedevice described. In fact, many features of the invention are applicableto devices operating upon traveling yarns for purposes other than thecatching of slubs, for example, to devices for cleaning, dyeing, orotherwise treating yarns.
